Manage GPU instances, templates, volumes, serverless endpoints, SSH keys, and billing on Vast.ai.
Command is
vastai(lowercase). Always use--rawfor machine-readable JSON output.
# PyPI (recommended)
pip install vastai
vastai set api-key <YOUR_API_KEY> # Authenticate (one-time); Create API Key in account at https://console.vast.ai/manage-keys/
vastai show user # Verify auth + check balance
vastai create ssh-key ~/.ssh/id_ed25519.pub # Register SSH key (do BEFORE create)
vastai search offers 'gpu_name=RTX_4090 num_gpus=1 verified=true direct_port_count>=1 rentable=true' -o 'dlperf_usd-'
# Note the offer ID from the output
vastai create instance <OFFER_ID> --image pytorch/pytorch:@vastai-automatic-tag --disk 20 --ssh --direct
# Automatically grab appropriate image tag; Response: {"success": true, "new_contract": <INSTANCE_ID>}
vastai show instance <INSTANCE_ID> # Poll until actual_status == "running" (see Instance status values below)
vastai ssh-url <INSTANCE_ID> # Get SSH connection string
vastai copy local:./data/ <INSTANCE_ID>:/workspace/ # Upload files
vastai destroy instance <INSTANCE_ID> -y # Clean up (stops all billing; -y skips confirmation)
API key: https://console.vast.ai/manage-keys/
Available on every command:
--api-key KEY Override stored API key
--raw Output machine-readable JSON (agents should always use this)
--full Print full results (don't page with less)
--explain Show underlying API calls (useful for debugging)
--curl Show equivalent curl command
--no-color Disable colored output
--url URL Override server REST API URL
--retry RETRY Set retry limit for API calls
--version Show CLI version
Search commands accept filter expressions. Operators: =, !=, >, >=, <, <=, in, notin.
# Examples
'gpu_name=RTX_4090 num_gpus=1' # Exact match + numeric
'gpu_ram>=48 reliability>0.95' # Greater-than filters
'geolocation=EU dph_total<=2.0' # Region + price cap
Common filter fields: num_gpus, gpu_name, gpu_ram, cpu_ram, disk_space, reliability, compute_cap, inet_up, inet_down, dph_total, geolocation, direct_port_count, verified, rentable
Common sort fields: score (default — overall value), dlperf_usd (DL perf per dollar), dph_total (price), num_gpus, reliability
vastai show instances # List all your instances
vastai show instances-v1 # Paginated instances with full filter/sort/cols support

# Response includes "new_contract": <id> — that is your instance ID
vastai launch instance --gpu-name RTX_4090 --num-gpus 1 --image pytorch/pytorch
vastai start instance <id> # Start stopped instance
vastai stop instance <id> # Stop (preserves disk, no GPU charges)
vastai reboot instance <id> # Stop + start
vastai destroy instance <id> -y # Delete permanently (irreversible; -y required for non-interactive use)
vastai destroy instances <id1> <id2> -y # Batch delete (-y skips confirmation prompt)
vastai label instance <id> --label "training-run-1" # Tag instance
vastai update instance <id> # Recreate from updated template
vastai prepay instance <id> # Deposit credits into reserved instance
vastai recycle instance <id> # Destroy + recreate

create instance flags:
--image IMAGE — Docker image--disk DISK — Local disk in GB--ssh / --jupyter — Connection type--direct — Faster direct connections--label LABEL — Instance label--env ENV — Env vars and port mappings, e.g. '-e TZ=UTC -p 8080:8080'--onstart FILE — Path to a startup script file--onstart-cmd CMD — Startup script as inline string (for longer scripts use --onstart or gzip+base64 encode)--bid_price PRICE — Interruptible (spot) pricing in $/hr--template_hash HASH — Create from template--create-volume ID — Attach new volume--link-volume ID — Attach existing volume--cancel-unavail — Fail if no machine available (vs. create stopped)Instance status values:
actual_status | Meaning |
|---|---|
null | Provisioning |
created | Instance created, not yet provisioned |
loading | Image downloading / container starting |
running | Active — GPU charges apply |
stopped | Halted — disk charges only |
frozen | Paused with memory — GPU charges apply |
exited | Container process exited unexpectedly |
rebooting | Restarting (transient) |
unknown | No recent heartbeat from host |
offline | Host disconnected from Vast servers |
Poll loop warning: If
actual_statusbecomesexited,unknown, orofflineit will never reachrunning. Always add a timeout and error branch — otherwise your script loops forever while disk charges accrue. Destroy and retry with a different offer.
Charges: Storage charges begin at creation. GPU charges begin when status reaches
running.
Interruptible (spot) instances are priced below on-demand instances, but can be interrupted at any time by another user with a lower bid. Note: search offers --type bid exposes min_bid, but create instance defaults to on-demand at dph_total unless you pass --bid_price <floor>. Always pass --bid_price after a --type bid search, otherwise the instance will be rented as an on-demand instance/price instead of as an interruptible.
When outbid, the instance moves to stopped (not destroyed) and storage charges continue. Resume by raising the bid via update instance --bid_price.

Permission denied | SSH key not attached | vastai create ssh-key before create instance |
Connection refused | Instance not yet running | Poll show instance <id> until actual_status == "running" |
Hangs on destroy instance | Confirmation prompt waiting for input | Add -y flag: vastai destroy instance <id> -y |
